RESUMO

To study the chemical constituents of Rhizoma of Coniogramme japonica. The Rhizome of C. japonica were extracted with ethanol and the chemical constituents were separated by chromatography technique, and their structures were determined by spectral analysis. Six compounds were isolated and identified as butyl 2-formyl-5-butoxymethyl-1 H-pyrrole-1-butanoate (1), pterolactam (2), 5-hydroxymethylfurfural (3), methyl linoleate (4), trilinolein (5), dehydrovomifoliol (6). All compounds are isolated from the genus for the first time, and the compound 1 is a new compound.
